The Hollywood Reporter has put it best:
The network has given a put-pilot with series penalty commitment to a live-action comedy from MacFarlane and the writers behind summer box office hit Ted...


Series penalty commitment?!?!?

Ignore the gibberish in the first part of the sentence and just focus on the fact that Seth MacFarlane, Fox, and the Ted writers are all getting together to write a TV show about a couple guys whose fathers move in with them. MacFarlane will executive produce and, let's face it, probably try to find a way to sing on the show.

This is MacFarlane's nine millionth collaboration with Fox, including The Winner, Family Guy, The Cleveland Show,  and American Dad. Okay. Fifth. But that's still a lot. I mean, how many development deals have you struck with Fox?

Probably zero, I bet.
